I have just done a search on the running out of stack pages. I'm not sure what browsers and OS are getting the problems here but the first 2 pages I found involve Internet Explorer 5 and Windows 98.

Apparrently, the problem can be resolved by adding the line

MinSps=4

to the [386Enh] section of System.ini and rebooting. Both sites suggest increasing the number of pages in increments of 4 if problems persist. Each stack page uses 4 Kb of system memory.
